Colleagues mourn murdered prison guard Jayme Biendl

A corrections officer who had raised concerns about being the sole guard in the chapel of a Washington state prison was strangled there over the weekend, and an inmate serving a life sentence is the primary suspect, authorities said Sunday.

Jayme Biendl, 34, was found dead Saturday night in the chapel at Monroe Correctional Complex about 30 miles northeast of Seattle, Department of Corrections spokesman Chad Lewis said. She had been strangled with a microphone cord.
